Uv unwrapping, creating and applying displacement / normal maps to a model

As you can see i keep learning more 3d rendering / and detailing, down here you can tell that i kind of start to handle the way to make normal maps / sculpt maps and add them to a lower poly character, it allows for more details to be drawn on a lower poly model, here mostly muscle details / shadowing / scars / veins in the arms, some burnt scars on the torso too, and more subtle muscle definition too, some specular maps adds some extra detail on the lightning on the model too, i didn't go too crazy with it but it's a start :

Some shots at different angles of light touching the character :

with multiple source of light and other kind of setup with how light bounce on the texture

The tedious part is to unwrap the uv's of the model , but i suggest using a program called uvlayout 2 it's very very effective and fast for unwrapping :

Here is a special kind of displacement map you can use as a normal map but also as a specular level / glossiness map (multipurpose map generated with zbrush )

And what you barely ever use anymore if you make vectorial displacement map, but some other engines might only use normals like these :

That's whati've been doing these past 24 hours.
